bPECIFICATON 'forming part of Letters Patent No. 336,892, dated March 2, 18?. 6.

Application filed December 3D, 1885. Serial No. 187,172. (No modell) To @ZZ whom, it may concern.-

Beit known that I, JAMES M. GALENDER, a citizen of the United States, residing at Milton, Mahoning county, Ohio, have invented a new and useful Improvement in Nut-Locks, of which the following is a specification.

My invention consists of a metallic plate, preferably of steel, formed with a bolt-hole, and having its ends doubled or bent over to come in contact with the underside of the nut, as hereinafter more particularly described.

In the drawings forming a part of this specification, Figure l represents a longitudinal section ofthe nut-lock, and Fig. 2 is a plan of the same.

The nut-lock is a thin steel plate formed with a bolt-hole, s. and having its ends bent over, as shown, and partially surrounding the bolt b. The ends of the nut-lock, when thus bent, are of a loop-like forni, a, having depressions a opposite each other in the top and bottom. The Lipper and lower parts of the plate or nut-lock are divergent from depressions a to the bolt-hole s. When nut ny is screwed down on bolt, b, it forces down the upper part, a, of the nut-lock until the upper and lower depressions or parts, a', are in contact. By screwing the nut still farther down only the upper and lower parts, a a3, of the nut-lock between depressions a are comthe upper and lower parts, a a3, divergent 45 from depressions a to the bolt-hole, substantially as described.
